The problem

A consumer app on iOS, Android and web needed on-chain features that ordinary users could use without thinking about wallets or transactions.

Outcome

Live on iOS, Android and web

Stack

  • TypeScript
  • Node.js
  • EVM
  • ethers.js
  • web3.js

What I built

Wallet and authentication flows, client-side contract calls, event indexing and transaction handling, plus backend services keeping on-chain state in sync with off-chain application logic. I documented the contract interfaces and led the handover to the internal team.
